Abstract: PURPOSE: To remove error by a gyro drift or the like in a posture stabilizing device having a gyro. CONSTITUTION: A drift correction loop for correcting error by a gyro drift or the like is provided in addition to a control loop. The drift correction loop comprises two rotational angle generators 24, 34 that detect rotational angles around two axis lines of a body to be controlled with respect to a base table and two comparators 25, 35 that compare output signals of the rotational angle generators 24, 34 with output signals of instruction generators 41, 42 to respectively obtain the deviations. The output signals of the comparators 25, 35 is fed back to the control loop. The control loop comprises a reference mode judgment device 45 and judges an automatic mode or a manual mode. In the automatic mode, predetermined values are supplied to the comparators 25, 35 instead of the output signals of the instruction generators.

Filed: 1978-09-26
Abstract: PURPOSE: To make opening and closing the blades automatically and surely by a mechanism wherein the blades are opened by the revolution of the ventilation fan motor, and are closed by the force of spring thru the disengagement of the clutch when the motor stops its revolution.  
     CONSTITUTION: At the rear end of the motor 2 which rotates the ventilation fan 31, the extended shaft 3 is connected on which spring thrusts 4, 6 are fixed, and the clutch body 5 is loose fit on the shaft 3 between the spring thrusts 4, 6. The clutch body 5 is being pushed by the springs 7, 8 and their given pressure is designed to make the clutch body 5 slip when the applied load exceeds the preset value. When the shaft revolves at a speed over the preset value, the clutch body 5 engages with the inner gear 10a of the ring 10, and the revolution speed is reduced by the gears 9W19, and the revolving force is transmitted to the blades 33a and 33b which are energized to the closing direction by the operating switch 42 and the spring 37 thru the chain 32, wires 40, 44 from the sprocket 27. Accordingly, blades are opened when the motor revolution exceeds the preset value, and are closed when the motor stops its revolution.

Title: Detection of moving object and transient event using rotary strip aperture image measurement
Inventor: RAFANELLI GERALD L
IPC: G01S17/90
Filed: 1997-04-21
Abstract: PROBLEM TO BE SOLVED: To detect a moving target with a simple expanded structure having a light weight by synthesizing an equivalent full circular aperture image from the frames of a target scene from which the image is formed through a telescope when a strip aperture provided with a signal processor rotates around the optical axis of the telescope. SOLUTION: A rotary aperture image-generating radiation sensor system 10 is formed in a satellite containing a stationary section 13 having an earth- oriented antenna 13a. When a primary reflector 12a rotates around the optical axis of a telescope 11, many image frames of a target scene visualized through the telescope 11 are matched to each other. An image rotation removing device 16 generates a stationary image by reversely rotating the image during the integrating operation of a detector. The target scene is projected and visualized on a detector array 17 arranged in the focal plane of the telescope 11 coupled with a signal processor 18 which processes the image frames. The signal processor 18 synthesizes an equivalent full circular aperture image by individually processing and combining the image frames and detects a moving target.

Abstract: PURPOSE:To obtain a carrier especially enhanced in its adsorbing capacity of a sulfur compound by heat-treating clay mineral within a specific temp. range at first to change the structure thereof and exchanging the magnesium ion of the clay mineral with a transition metal ion. CONSTITUTION:When double chain structure type clay mineral is heat-treated at 400-800 deg.C at first, the water present in the tunnels of the structure of this clay mineral is removed and, next, the bonding force of octahedral Mg-O of the MgO layer constituting a crystal is lowered and a magnesium ion becomes easy to elute in water. Herein, the clay mineral is immersed in an aqueous solution containing a transition metal ion such as Co<2+> or Ni<2+> to easily exchange the magnesium ion with the transition metal ion. Therefore, a carrier capable of adsorbing a sulfur compound by the formation of a complex of the transition metal ion and sulfur is obtained.

Abstract: PROBLEM TO BE SOLVED: To always eliminate the inclination between a recording medium and an objective lens by detecting the inclination of the recording medium or between the recording medium and the objective lens and adjusting respective currents flowing through two pieces of focus coils based on the detected inclination. SOLUTION: Focus drive force 24a is generated in the focus coil 15a for a flow of magnetic flux 38a by the current 23a, and moment of force 26a is generated around a support center 25. Similarly, the focus drive force 24b is generated by the magnetic flux 38b and the current 23b, and the moment of force 26b is generated. Thus, the moment of force 27 applied to a movable part containing the objective lens becomes the sum of the currents 23a and 23b, and the moment of force 27 is changed in the direction and the amount according to a difference between the currents 23a and 23b. At this time, since the sum of the whole currents becomes the focus drive force of the movable part, the moment of force 27 is changed while following the focus of the objective lens.

Abstract: PURPOSE: To obtain a given Al wafer pattern for low speed of etching from side face through the process consisting of changing Al wafer into porous alumina through selective chemical treatment using photo-resist as protective film, and etching the alumina.  
     CONSTITUTION: The Al wafer 3 having attached to the surface of a semiconductor substrate 2 having insulating film 6 is chemically treated using patterned photo- resist 1 for changing the portion at the range not covered with the protective film 1 thereof into porous alumina 4. At this time, the portion at the range convered with the protective film 1 of the Al wafer 3 does not change at all, and the remainder portion become almost to the protective film 1 in size. Next, etching treatment is made with etching liquid of which the etching speed for porous alumina 4 is  sufficiently higher than that for Al 3 or non-porous alumina 5. Since the non- porous alumina 5 serves as good pro tective film, a low rate is developed of etching  from the side face of the Al wafer 3 so that Al pattern almost equal to photo-resist  pattern in size can be obtained.

Abstract: PROBLEM TO BE SOLVED: To automatically calculate the correcting value of a scale factor in a main scanning direction by obtaining a correcting efficient for adjusting a scale factor from the values measured first and second of a distance between two marks at the time of storing read image data. SOLUTION: Relating to an image forming device 100, two straight lines are parallelly drawn in a sub-scanning direction just behind a white reference panel for shading correction.

Then the ratio of a distance between the marks on a memory at the time of 1st scanning and that at the time of 2nd scanning becomes a value obtained by multiplying the errors of scale factors by a printer and a scanner. The operation part 54 makes such a setting as correcting a variable power rate in the main scanning direction based on this numerical value.

Abstract: PROBLEM TO BE SOLVED: To reduce a change in light intensity between pitches even when there is a slight shift between them, in the case when an LED chip bringing about a sharp rise and fall in the distribution of the light intensity is applied as a light source. SOLUTION: Dot patterns of which the focuses shift from each other are cast on a photosensitive material. These dot patterns are shaped like hills of which the rises and falls are gentle, and overlapping parts of light gain in quantity. Therefore parts of the bases of the adjacent dot patterns affect each other. When adjacent LED chips shift from each other in the approaching direction, for instance, the overlapping parts of light in the case of the dot patterns of which the focuses are at positions shifting from each other gain in quantity gradually as shown by an arrow A. Therefore no sharp change takes place and, as a result, no large error in the light intensity is brought about.
